Abstract:
The farmer field study was carried out during 2016 at village Saida, Takhatpur Tehsil in Bilaspur district of Chhattisgarh to evaluate the “Long term effects of rice establishment methods on physical properties and rice productivity in Vertisols of Chhattisgarh plain”. The trial was laid out in Randomized block design with twelve replications and three treatments in rice based cropping system in Vertisols. The study on the long-term effect of rice establishment methods on soil biological properties and crop productivity were evaluated after harvest of rice crop. In this study, three rice establishment methods i.e. transplanting, broadcast-biasi and direct seeded line sowing were laid in main treatment. A study was undertaken to characterize the soil resources of the investigation field. The residual effect of rice establishment methods on soil biological properties like urease activity, soil microbial biomass, soil microbial biomass nitrogen and carbon dioxide evaluation were significantly affected by the treatments. Urease activity, soil microbial biomass, soil microbial biomass nitrogen and carbon dioxide evaluation of soil was significantly higher under direct seeding rice followed by biasi and lowest under puddled transplanted rice.
